Characteristics of some previously described North Amer- 
ican Coleopterous Insects, and descriptions of others 
which appear to be new, in the Collection of Mr. Abra- 
ham Halsey: By T. W. Harris, M. D., Librarian 

of Harvard University. Communicated Dec. 23, 1835. 


. 1. Currvrva quaprimacutata, Pal. de Beauvois. 
8 Thorax black, quadrate, broadest at base, with obtuse- 
cx ly rounded angles, and an impressed dorsal line: elytra 

, with punctured striz, piceous black, obscurely rufous at 
“> base, and with an oblong oval rufous spot near the tip.

Thorax almost square, diameters equal, a little broadest 
, at base, angles very obtusely rounded, pedicle short, later- 
al edge not recurved at tip. Elytra with one impressed 
point at the commencement of the rufous terminal spot, 
“on the second interstitial line, contiguous to the third stria ; 
“fourth interstitial line impunctured. Intermediate tibie 
~ not dentated on the outside, but beset with short bristles. 


66 NORTH AMERICAN COLEOPTERA. 


Anterior thighs dilated, ra with the body beneath piceous 
black ; tarsi, and the other legs dark ferruginous. 

Notwithstanding the remark made by Mr. Say that, in 
the guadrimaculata, the interstitial lines are entirely with- 
out punctures, I believe this insect to be the one described 
by M. Pal. de Beauvois, although it has a single impress- 
ion on the second interstitial line. The description given 
by Count Dejean of his bipustulata, to which he refers M. 
Beauvois’s quadrimaculata, is deficient in some respects, 
the insect from which the description was drawn being, as 
he savs, in bad condition. Mr. Say also confounded the 
bipustulata and quadrimaculata in his description in the 
Philosophical Transactions; but, subsequently, corrected 
the mistake, and stated that the thorax of the Fabrician 
species is proportionably longer than that of the quadri- 
maculata. 


2. Crivina spHmRIcOLLISs, Say. 


Thorax subglobose, broadest behind the middle, with a 
dorsal impressed line ; elytra greenish black, with distant 
punctured striz ; tibia and tarsi dark rufous. 

Length 19 hundredths of an inch. 

C. sphericollis, Say. Trans. Philos. Soc. Phil. N.S. 
vol. il. p. 23. 


Halsey’s Collection, No. 10. 

Head black, somewhat bronzed. Body beneath and 
thighs piceous black. Thorax longer than wide, somewhat 
gibbous behind the middle; the pedicle long, as in the 
globulosa, S. Anterior tibie not digitate on the outside ; 
apex prolonged, spiniform, with a stout spine opposed to 
it beneath the tip, and a deep indentation before the mid- 
dle of the inside. From these characters derived from 
the tibia, and from the globular form of the thorax this 
species must belong to M. Bonelli’s genus Dyscurnivs. 


NORTH AMERICAN COLEOPTERA. 67 


3. CHianius mstivus? Say. © 


Thorax cordato-quadrate, with the head greenish cu- 
preous, densely punctured; elytra purple-black, with 
punctured striz, and granulated, subconvex interstitial 
lines ; antenne and feet rufous. 

Length 66 hundredths of an inch. 

C. estivus? Say. 'Trans. Philos, Soc. Phil. N.S. vol. 
li. p. 62. 

Halsey’s Collection, No. 16. Two females. 

Body beneath rufo-piceous. Head cupreous, green be- 
fore, densely punctured ; labrum ferruginous, entire. Tho- 
rax cupreous, tinged before and on the edge with green, 
with large distant punctures ; quadrate, rather longer than 
broad, widest a little before the middle, rounded on the 
sides before and contracted behind the middle, with the 
hind angles almost straight or slightly excurved and suba- 
cute; dorsal line not widely sulcated, almost obsolete be- 
hind; lateral grooves short, wide, neither reaching the 
middle nor the base. 

In other respects this insect agrees with Mr. Say’s de- 
scription, except in being rather smaller. 

Compared with C. purpuratus, mi, Ms. this species, 
besides being much larger, has the thorax much more 
cordiform, (or contracted behind,) longer, not near so con- 
vex, with the dorsal line not so widely and distinctly im- 
pressed, the basal lines not so oblique, of a decidedly cu- 
preous colour tinged with green, instead of being purple 
as in that species ; and the elytra are of a much more ob- 
scure purple-black. The form of the body is much the 
same in both. 


4, CoLyMBETES sTAGnints, Say. 

Oval, black, beneath piceous; vertex with two spots 
and the anterior margin rufous ; elytra depressed, with a 
whitish sub-marginal abbreviated line. 


68 NORTH AMERICAN COLEOPTERA. 


Length 37 hundredths of an inch. 

C. stagninus, Say. Trans. Philos. Soc. Phil. N.S. vol. 
ii. p. 100. 

fHalsey’s Collection, No. 88. 1 female. 

Body oval, obtuse before and behind, and somewhat 
depressed ; above black, opaque, covered with obsolete 
orbicular or oval granules ; beneath piceous. Elytra with 
three dilated lines of irregular punctures, confused at tip ; 
and a whitish line originating near the middle of the later- 
al submargin, and ending before the tip. In all other re- 
spects the specimen agrees with Mr. Say’s description. 

Compared with the fenestralis, S. this insect is more 
obtuse behind, much more depressed, and rather smaller 
in size. The granulations of the elytra are almost obso- 
lete, and the color is destitute of the brassy or metallic 
tinge of the fenestralis ; while the punctured lines and 
white submarginal stripe render it quite a distinct and 
easily recognized species. It is broader, more depressed, 
and much more obtuse behind than the seriatus, S. and 
not so convex and acute behind as the erytropterus, of the 
same author. 


5. CorymBeres ciypiicus, Say. 

Fuscous-brown, thorax paler; beneath piceous; elytra 
deeply striated. 

Length 21 hundredths of an inch. 

C. glyphicus, Say. ‘Trans. Philos. Soc. Phil. N.S. vol. 
ll. p. 99. 

Halsey’s Collection, No. 39. One.male. 

Head and thorax minutely punctured, rufous, darker on 
the summit. Elytra impunctured, smooth, fuscous brown, 
the outer margin obsoletely rufous, &c. In other respects 
the specimen corresponds exactly with Mr. Say’s de- 
scription. 


NORTH AMERICAN COLEOPTERA. 69 


The body is oblong-oval, like that of C. bicarinatus, 8., 
depressed, and equally rounded before and behind. ‘This 
insect is readily recognized by its lavigated and deeply 
striated elytra. Compared with the bicarinatus, as to 
form, it is more obtuse behind, and more depressed ; while 
its color is rather of a fuscous than a reddish brown. 


6. OxyTEeLus ruauLosus? Say. 


Black ; head, thorax and elytra covered with minute 
longitudinal wrinkles ; thorax trisulcated ; elytra piceous 
brown, 

Length from 19 to 20 hundredths of an inch. 

O. rugulosus? Say. Descriptions, Harmony. p. 47.— 
Trans. Philos. Soc. Phil. N.S. vol. iv. p. 460. 

ffalsey’s Collection, No. 46. 

Head behind longitudinally wrinkled, before nearly 
smooth, with a deep transverse indentation in front, be- 
yond which the head is very much depressed; a longi- 
tudinal abbreviated groove on each side above the eyes, 
and a very short indentation on the vertex. Antenne 
black, opaque, Jaws and palpi rufous. Thorax trans- 
versely quadrate, broadest before the middle, anterior 
margin straight, hmder margin and angles, rounded, ante- 
rior angles rectangular, obtuse ; disc widely indented or 
depressed each side of the centre, covered with minute 
longitudinal wrinkles, and with three longitudinal, ap- 
proximated grooves, of which the middle one is widest 
before, and the lateral ones behind. Tergum black, pol- 
ished ; under a high magnifier it will be seen to be cover- 
ed with mute punctures, which, however, are invisible to 
the naked eye. 

Closely allied to an undescribed species from Massa- 
chusetts, (my No. 1405,) proportionally more slender, 
much smaller, with a longer thorax, the anterior angles of 
which are much more acute, the base more prolonged in 
the middle; the elytra darker, &c. &c. 


70 NORTH AMERICAN COLEOPTERA. 


7. Tacuyrorus ma@stus, Say. 

Piceous, sericeous ; antenne, feet, and vent honey yel- 
low. 

Length 16 hundredths of an inch. 

T. mestus, Say. Descriptions, Harmony, p.53.—Trans. 
Philos. Soc. Phil. N. S. vol. iv. p. 466. 


Halsey’s Collection, No. 202. 

Body covered with sericeous, glossy pubescence, chang- 
ing the shade of color in different positions. Thorax and 
elytra obsoletely edged with rufous, &c. &c. 

Compared with Tachyporus fumipennis, S. it is smaller 
and more slender; the abdomen is more elongated ; the 
thorax rather longer, and consequently more gradually 
narrowed and rounded before. 


8. EQLATER MILITARIS.* 

Black ; elytra whitish, outer edge and elongated sutu- 
ral spot behind black. 

Length 30 hundredths of an inch. 

Halsey’s Collection, No. 58. 


Body black. Clypeus moderate, depressed, rounded at 
tip. Antenne piceous, not much longer than the thorax, 
not very robust; second and third joints obconical, nearly 
globular, much smaller than either of the succeeding ones ; 
the second rather shorter and thicker than the third; the 
fourth and remaining joints to the last triangular, and 
equal; terminal joint regularly oval. ‘Thorax short, and 
with the head minutely punctured, polished, black ; hairs 
thin, inconspicuous; posterior angles carinated, very 
slighty excurved, acute. Scutel convex, acute and slight- 
ly elevated behind. Elytra whitish, with strize of dilated 
punctures ; the exterior edge black, and an elongated 
black spot upon the suture, widest behind, and suddenly 
attenuated before the middle, extending in a mere line 


* Plate I. fig. 1. 


NORTH AMERICAN COLEOPTERA. 71 


nearly to the scutel. Feet piceous; tarsal joints pro- 
gressively shorter and smaller to the last, not lobed be- 
neath ; claws simple. 

This apparently new species nearly resembles the lu- 
gubris of M. Pal. de Beauvois in form ; but it is a much 
smaller insect ; the thorax is more polished, with the punc- 
tures less apparent, the hinder margin not so deeply 
emarginated for the base of the elytra, and the posterior 
angles rather more excurved. ‘The elytra, taken together, 
are widest just before the middle, and are not so much 
contracted until towards the tip. The antenne and tarsi 
are widely different in these two species. 


9. Exarer rusricoius, Herbst. 

Black ; thorax above dull crimson or rufous, beneath 
black; edge of the clypeus depressed ; third joint of the 
antennz longer than the second, obconic ; vertex reddish ; 
nails simple. 

Length 50 hundredths of an inch.

Body punctured, and with small, depressed, rufous hairs. 
Head black, dull crimson on the disc in a good light; mi- 
nutely punctured ; edge of the clypeus deflexed over the 
front. Antennze with the second joint rufous, obovate, 
a little more than half the length of the third, which is 
obconic. Thorax dull crimson above, the anterior edge, 
lateral margin, spines, and breast black. Elytral striz

with round, close punctures; interstitial lines convex, 
punctured. Disc of the postpectus with a reddish spot 
each side. An obsolete reddish line on the sides of the 
last three ventral segments. [eet beneath piceous, not 
lobed ; nails simple. 

Inhabits New Hampshire, Pennsylvania, and Illinois. 

A single specimen ‘of this insect, captured in New 
Hampshire, and preserved in the Cabinet of the Boston 
Society of Natural History, has afforded me the oppor- 
tunity of drawing up the preceding description, which is 
inserted in this place for the purpose of pointing out the 
characters which distinguish this species from the Hlater 
collaris of Mr. Say. It 1s, without doubt, the true rubri- 
collis of M. Herbst. Mr. Say* says that “ it is the verézci- 
nus, Beauvois,” also, and that he “does not know which 
[name] has the priority.”{ It is not to be found described 
in the 12 hvraisons of M. Pal. de Beauvois’s “ Insectes,” 
the last of which was published in 1818; and as Herbst 
published the 10th volume of his work in 1806, the name 
of rubricollis, given by him, has undoubtedly the priority, 
over that of verticinus. 

It should be observed that the crimson color of the 
thorax, d&c. of this insect fades to a dull red or rufous col- 
our after it has been some time preserved. 


10. Eucnemts rrianauLaris, Say. 


Black, sericeous; antennz two thirds the length of the 
body ; thorax with a carinated line behind the middle, an- 
terior margin piceous; pectus channelled, to receive the 
antenne, each side of the middle; elytra punctured, and 
with only a subsutural stria. 

Length 18 hundredths of an inch.

Elater triangularis, Say. Journ. Acad. Nat. Se. vol. 
ul. p. 170. 

Euenemis triangularis, Say. Ms. No. 13. 

Eucnemis longulus, Dejean, according to Leconte, 

Halsey’s Collection, No. 69. 

Body black, sericeous with short, scattered, yellowish 
hairs. Head beneath with a deep longitudinal furrow on 
each side of the clypeus. Antenne dark piceous ; first 
joint arcuated, thickened ; second very short obconic, and 
arcuated at base; third nearly as long as the first, obcon- 
ic ; remaining joints elongated triangular, serrate within ; 
terminal joint elliptical, attenuated at base, subacutely 
rounded at tip. Thorax quadrate, convex before, emar- 
ginate:' each side of the base; hinder angles produced, 
incurved, acute ; the surface minutely punctured, with a 
deep indentation at the base before the scutel, a fainter 
one before each of the posterior spines, and an obsolete 
carinated line from the middle of the disk to the basal in- 
dentation. Elytra elongated, moderately narrowed from 
the shoulders to the tip, which is obtusely rounded ; sur- 
face not regularly striated, but densely and irregularly 
punctured, and with a subsutural depressed longitudinal 
line most distant behind the middle. Feet pale rufous. 

Inhabits New Hampshire, Indiana, Missouri, &c. 

Mr. Say gave me the name for this species, which, 
however, does not entirely agree with his descriptions ; 
the antennz being larger, the thorax carinated behind, 
and the elytra with one stria. Notwithstanding these dif- 
ferences it is most probably the true . triangularis of 
Mr. Say. 

The variety, indicated, in the Journal Academy Nat. 
Sc., as having the elytra striated and dull rufous at base, 
has been separated and described as a distinct species, in 
Mr. Say’s Manuscripts, under the name of Hucnemis hu- 
meraiis. Besides these two species, Mr. Say refers to the 


10 


74 NORTH AMERICAN COLEOPTERA. 


same genus his Haters muscidus, unicolor, and clypeatus, 
his Melasis ruficornis, and eight new species, inhabiting 
the United States. 


11. Lampyris nienicans, Say. 

Brownish black ; thorax with an elongated rosaceous 
or sanguineo-rufous spot each side within the margin. 

Length 25 hundredths of an inch. 

L.mgricans, Say. Journ. Acad. Nat. Sc. vol. iii. p. 179. 

Halsey’s Collection, No. —. 

The thoracic spots are decidedly rosaceous in recent 
specimens, but seem to become sanguineo-rufous after 
being some time kept. The terminal joint of the antennz 
is ovate, attenuated, or subacute at tip; and the other 
jomts are moderately dilated. 

It has not, as yet, been discovered in Massachusetts. 


12. Lampyris DECIPIENS.* 

Brownish black or fuscous; lateral dilated margins of 
the thorax rosaceous, or sanguineo-rufous; tip of the ab- 
domen immaculate. 

Length from 22 to 26 hundredths of an inch. 

LL. decipiens, Harris, Catalogue, p. 500. 

Halsey’s Collection, No. 77. 

Body oblong, nearly linear, brownish black, opaque. 
Antenne nearly linear, slightly dilated and subcompressed ; 
terminal almost as long as the penultimate joint, linear, 
obtuse at tip. Thorax polished black from the base to 
the front edge, the dilated and depressed lateral margins 
above and beneath rosaceous in recent and sanguineo-ru- 
fous in old specimens. Elytra brownish black, opaque, 
minutely granulated, and with two slightly elevated lines. 
Abdomen entirely black beneath. 

Inhabits Massachusetts. 


* Plate I. fig. 2. 


NORTH AMERICAN COLEOPTERA. ves 


Differs from L. nigricans in not having the lateral mar- 
gin as well as the disc of the thorax black, in the form of 
the last joint of the antennee, &c. &c. It somewhat re- 
sembles L. laticornis, Fabricius, a much larger and pro- 
portionally broader species, which has more dilated an- 
tennee, and the sides of the last abdominal segment yel- 
lowish white both above and beneath. 


13. ANOBIUM PELTATUM. 


Reddish brown, sericeous ; thorax transverse, obsolete- 
ly carinated in the middle of the base; elytral striz im- 
punctured, slender, not profound. 

Length from 17 to 18 hundredths of an inch. 


Halsey’s Collection, No. 221, male and female. 

Last three joints of the antennz in the male oblong- 
oval, not much elongated ; remaining joints triangular, di- 
Jated, serrate. Inthe female the joints of the antenne are 
proportionally shorter than those of the male, the two or 
three basal ones transverse, the rest progressively longer 
but all triangular, except the last, which is oblong-oval. 
Thorax transverse, not abruptly contracted before, basal 
edge slightly bisinuated, basal angles wanting, margin reg- 
ularly rounded from the base to the anterior angles, which 
are subacute ; disc not very convex, with an abbreviated, 
almost obsolete carina near the base. Elytra sericeous, 
with faintly impressed, siender striz, which are impunc- 
tured ; the outer and inner ones (as in most other species) 
coalescing at the tip. Tarsal joints short, stout; the first 
long-obconic, longer than either of the others ; the second 
about two thirds the length of the first, obconic; third and 
fourth subtransverse, each produced beneath in the form 
of a cordiform lobe; the fourth emarginated above to re- 
ceive the fifth jot, which is longer than the penultimate, 
attenuated at base, gibbous at the end, and terminated 
Jaterally by very small simple claws. 


76 NORTH AMERICAN COLEOPTERA. 


This species differs from the carinatum, of Mr. Say, in 
having the thorax shorter and wider both at base and tip, 
the strize of the elytra much less deeply impressed and 
impunctured, &c. &c. It approaches nearer to tenuestri- 
atum, Say, which, however, is much smaller, and has punc- 
tured stric. 

The tarsi of the pelfatum are short and thick, like those 
of the striatum, Fabricius, and carinatum, Say; but the 
penultimate and antepcnultimate joints are obviously lobed 
beneath, as they are in XyLetinus sericeus, Say. The 
antenne of this last insect hardly warrant its being sever- 
ed from thé genus Anopium ; they resemble considerably 
those of our peltatum, but the last three joints are not so 
distinctly elongated. 


14. Hisrer oprusatus.* 

Black, immaculate ; head with a transverse stria; tho- 
rax with two entire lateral striz ; each elytron cbsoletely 
indented in the middle of the base, transversely punctured 
at tip, with an entire marginal, oblique abbreviated hu- 
meral, four entire and two abbreviated dorsal si::cs; an- 
terior tibiee six-toothed on the outer edge. 

Length 36 hundredths, breadth 24 hundredths of an 
inch. 

Hf. unicolor? F. Say. Journ. Acad. Nat. Sc. vol. v. 
p. 33. 

Halsey’s Collection, No. 83. 

Body oblong oval, very obtuse before and behind, po- 
lished black, immaculate. External thoracic stria not 
abbreviated, but uniting behind with the inner one. Mar- 
ginal and abbreviated oblique humeral strize of the elytra 
very distinct; within the latter four dorsal strize, the third 
of which has an obsolete indentation near its origin; the 
fourth beginning a little farther from the base than the 


* Plate I. fig. 3. 


NORTH AMERICAN COLEOPTERA. ee | 


third; the subsutural stria obsolete from the base nearly 
to the middle; the stria between it and the fourth dorsal 
has an arcuated rudiment near the base of the elytron, is 
discontinued from thence to behind the middle, and is ab- 
breviated before the termination of the other dorsal striz. 
A transverse series of obsolete punctures connects the 
posterior terminations of the second dorsal and subsutural 
strie. Last abdominal segment very obtusely rounded, 
and, with the penultimate, exposed, and densely punctured. 
Anterior tibia six-toothed on the outer edge, the terminal 
tooth emarginatd, and a minute tooth on the truncated tip 
just within the emarginated tooth. 

Is not this the species named unicolor, F. by Mr. Say, in 
his remarks on H. depurator in the Journal Acad. Nat. 
Sciences? The unicolor is described by Fabricius as 
having the anterior tibiee tridentate, and the elytra oblique- 
ly tristriated ; characters which do not justify us in apply- 
ing the same name to our insect, which agrees no better 
with the wnicolor described by M. Boitard in the “ Manuel 
d’Entomologie.” 


15. ‘Trox capinuaris, Say. 


Clypeus rounded at tip, not reflexed at the sides; ely- 
tra with longitudinal series of hispid tubercles and alter- 
nating capillary elevated lines : 

Length 42 hundredths of an inch. 

T. capillaris, Say. Journ, Acad. Nat. Sc. vol. ii. p. 238. 


flalsey’s Collection, No. 97. 

Body purplish brown, short obovate, very convex. 
Thorax completely covered with minute, dilated, or scale- 
like, ochraceous bristles ; dise with a longitudinal furrow, 
which is widened before; sides declivous, unequal; lat- 
eral margin entire; hinder margin widely emarginated 
each side, with a fringe of short bristles, which are inter- 
rupted between the middle and angles. Scutel triangu- 


78 NORTH AMERICAN COLEOPTERA. 


lar, obtusely rounded at tip, broad and truncated at base. 
Elytra of a fine purple-brown color, naked; tubercles 
sloping backwards, tufted with short, black bristles; the 
third, fifth, seventh, and ninth series, from the suture, lar- 
ger than the intervening ones; alternating with the rows 
of tubercles are small, threadlike, uninterrupted elevated 
lines. Anterior tibize enlarged towards the end, with a 
stout tooth before the tip, the latter being curved outwards 
and backwards, and emarginated or obtusely bidentate. 

Compared with the porcatus of Mr. Say, which this 
species somewhat resembles, it is smaller, more convex, 
more obtuse behind, and proportionally shorter. The 
clypeus and thorax are nearly alike in both, but the latter 
in the porcatus is not quite so gibbous before, nor is the 
longitudinal groove quite so much dilated in front, and the 
fringe of the hinder margin is uninterrupted. The elytra 
of the. capillaris have not the series of dilated punctures of 
the porcatus, are distinctly tuberculated, and it may fur- 
thermore be discriminated at once from its allied Ameri- 
can species by the slender elevated lines alternating with 
the rows of tubercles. 


16. Tanymecus tacmna, Herbst. 


Body oblong, densely punctured, piceous black, some- 
what cupreous, above with yellowish ashen, beneath more 
thickly covered with dirty white scales; rostrum carmu- 
lated before ; thorax with three denuded, blackish vitte ; 
elytra deeply punctured at base, punctato-striate, and with 
a callus behind. 

Length, to the tip of the rostrum, 26 hundredths of an 
inch.

NORTH AMERICAN COLEOPTERA. 79 


Body above rather sparingly covered with oval yellow- 
ish ashen scales, intermixed with short, dilated, depressed, 
whiter bristles; beneath with closer whitish scales and 
bristles. Rostrum, above, from the middle of the interocu- 
lar space, with a slender, raised line, discontinued before 
the tip, which is obsoletely and widely impressed. Eyes 
oval, black, rather prominent. Antenne very dark ru- 
fous ; the first joint extending nearly to the hinder margin 
of the eyes; the second joint thicker and rather longer 
than the third; the fourth to the seventh short, turbinated, 
gradually increasing in width; club oval, subacuminated. 
Thorax barrel-shaped, longer than wide, broadest before 
the middle, rugosely and densely punctured; above with 
three denuded, longitudinal, blackish lines, one in the mid- 
dle, and one on each side. Elytra at base conjointly emar- 
ginated, with the shoulders sloping obliquely backwards, 
behind which they are nearly twice the width of the tho- 
rax ; not very perceptibly widened in the middle ; gradu- 
ally attenuated; rounded behind; and each one subacu- 
minated at tip, before which is a slight elevation or callus ; 
at the sides and behind they are distinctly striated, the 
striee with distant oblong punctures ; before the strize are 
obsolete, and the punctures are larger and more distinct. 
Legs dark piceous, with scattered scales, and thicker bris- 
tles; posterior thighs obsoletely annulated with whiter 
scales near their tip, and, with the others, clavate and un- 
armed ; tibiae not spined at tip, the anterior pair some- 
what arcuated ; the hindmost ones, on the outside, near 
the extremity fringed with short, close-set hairs. 

This insect is evidently the Tanymecus lacena of Mr. 
Say, although he states his specimen to be only three 
twentieths of an inch in length. This measurement and 
the character given in his description, “ tip of each [ely- 
tron] with a short joint in the middle,” appear to be typo- 
graphical errors. M. Herbst says that the lacena is three

lines long. Our species seems to be allied to the confer- 
tus of M. Schoenherr, (« Genera et Species,” vol. ii. p. 
88.) which is said to be of the size of the palliatus, a much 
larger insect than the one here described. 

The /acena has the form of a Srrona, but the rostrum 
is more erect, the shoulders of the elytra are much more 
oblique, and the first joint of the antenne is rather long- 
er, &c. 


17. Crnrrinus! pILECTUS. 


Punctured, and with brassy scales ; scutel whitish ; third 
joint of the antennz twice as long as the fourth. 

Length, exclusive of the rostrum, 20 hundredths of an 
inch. 

Halsey’s Collection, No. 165. 

Body piceous black, densely punctured, and with elon- 
gated, brassy yellow scales. Head retracted to the eyes 
within the thorax, indented at the base of the rostrum. 
Rostrum as long as the head and thorax, slender, almost 
filiform, arcuated, slightly dilated over the origin of the 
antennee, piceous, minutely and remotely punctured. An- 
tennze inserted behind the middle of the rostrum, piceous, 
club rufous; third joint (second of the funiculus,) two 
thirds the length of the preceding, and twice the length of 
the following jot. Thorax, in the middle, longitudinally 
elevated, or almost carinated, covered with linear-lanceo- 
late scales, which converge from the sides towards the 
central carina. Elytra with acute, remotely punctured 
striz, and flat interstitial lines, each one of which is cov- 
ered with large, superficial, confluent punctures, and three 
series of lmear-lanceolate scales; an oblique elevation or 
callus before the tip of each elytron. Body, beneath, 
more densely covered with whiter, shorter, oval scales. 
Breast, before the anterior legs widely indented, not ca- 
naliculate, unarmed.

18. Cxrnrrinus suTor.* 

Black, punctured ; scutel with white, and body with 
yellowish, linear scales: third and fourth joints of the an- 
tenne together shorter than the second, subequal. 

Length, exclusive of the rostrum, 9 hundredths of an 
inch. 

Halsey’s Collection, No. 167. 

Body black, densely punctured, and with linear-lanceo- 
late yellowish or dirty white scales. Head indented at 
the base of the rostrum, retracted to the eyes within the 
thorax. Rostrum rather longer than the head and thorax, 
slender, arcuated, slightly dilated in the middle. Antenne 
inserted just behind the middle of the rostrum ; second 
joint (first of the funiculus,) longer than the third and 
fourth taken together ; the fourth joint rather shorter than 
the third. Thorax obtusely carinated, covered with lin- 
ear scales converging towards the central carina. LElytra 
with acute, remotely punctured stria, and flat, confluently 
but vaguely punctured interstitial lines, on each of which 
are three rows of linear scales. Scutel and posterior lobe 
of the thorax, in front of it, with white scales. Body, be- 
neath, more densely covered with oval, whitish scales. 
Breast deeply and widely indented before the anterior 
Jegs, not canaliculate, but with a long, pendent spine in 
front of each of the anterior coxe. 

This insect and the preceding one are evidently closely 
related. They agree in the form of the head, rostrum, 
thorax, and body: the eyes, in both, are large, oval, not 
prominent, but rather flat, separated above only by the 
base of the slender rostrum, and below by a still narrower 
space. ‘The thorax is conical, nearly as long as it is wide, 
tubulated before, without lobes behind the eyes, bismuated 
behind, and produced in the middle of the base before the

scutel. The elytra, taken together, are triangular, broad- 
est at base, with prominent shoulders, attenuated behind, 
the tip not truncated nor obtusely rounded, but subacute, 
and each with a callus before the apex. The hinder legs 
are wider apart than the two other pairs; the tibize are 
truncated and with an exceedingly minute hook at the in- 
side of the extremity ; and the thighs are unarmed. 

The characters of the genus Cenrrinus, as laid down by 
M. Schoenherr, do not all apply to these insects, which 
have not “the rostrum as long as the body,” nor “ the 
eyes distant,” nor “the thorax almost double the width of 
its length;” and “the club of the antennz” is not very 
distinctly “acuminated.” The antennze of the sutor ap- 
proach nearest to the description of those of Crnrrinus, 
but in the dilectus, the third joint is longer than it is rep- 
resented to be in this genus. Notwithstanding these dis- 
crepancies there is no other in which they can be so pro- 
perly arranged. . 

From Bariotus, they differ in the form of the body, 
which is not rhomboidal, nor rounded behind, nor with 
the anal segment exposed; and the antennal joints are 
more elongated, and not so closely connected. ‘They re- 
mind one (particularly the dilectus,) of the genus Bara- 
niNus, in general form, color, and length of the rostrum ;, . 
but cannot be referred to it on account of the structure of 
the breast, differences in the antennz, and other essential 
characters. 


* 19. Tomicus? pusILuus.

lated before ; posterior declivity of the elytra scabrous 
and hairy ; antenne and feet honey-yellow. 

Length 6 hundredths of an inch. 

Halsey’s Collection, No. 260. 

Dark chestnut-brown. Head covered with long, erect

hairs. Thorax with short hairs, intermixed with elevated, 
thick points, which are larger in front and sloping back- 
wards, smaller behind, and disappearing before the mid- 
dle, behind which the thorax is minutely punctured and 
subglabrous. Elytra subglabrous, minutely punctured, 
rough on the posterior declivity, which is covered with 
short hairs or bristles arranged in longitudinal rows. An- 
tenn and feet brownish yellow, the club of the former 
paler. 

This minute insect probably belongs to the genus Tomt- 
cus, but, being gummed on card, it could not be sufficient- 
ly examined. The body is cylindrical, obtuse and ob- 
liquely truncated behind. The club of the antennz oval, 
compressed, three-jointed ; the joints transverse, the last 
one semicircular and largest. The anterior tibize, the only 
ones which could be seen, were not very much dilated, 
and had a number of small teeth on the outer edge.

20. PRIoNUS LHZVIGATUS.* 


Chestnut-brown, subglabrous; thorax three-toothed ; 
the last two joints of the maxillary palpi nearly equal ; 
breast, in both sexes, hairy.

Cabinet of the Boston Soc. Nat. Hist. No. 1362. male, 
No. 1360. female. 

Body chestnut-brown, smooth. Head confluently punc- 
tured, channelled longitudinally between the eyes; last 
jomt of the maxillary palpi thicker but not much longer 
than the preceding one. Thorax short, transverse, mi- 
nutely punctured; lateral margin horizontal, somewhat 
dilated, with a prominent reflected tooth on the anterior 

angle and middle; the hinder angles slightly produced in

the form of a nearly rectangular, short tooth. Scutellum 
not obtusely and regularly rounded at tip, but subacute. 
Elytra elongated, somewhat oblong-quadrate, a little nar- 
rowed behind, slightly dilated at the middle of the sides, 
glabrous, not rugose, but with minute superficial punc- 
tures, and two longitudinal nearly obsolete elevated lines 
on each; sutural tip with a prominent spine. Body be- 
neath glabrous, obsoletely punctured ; breast with short, 
silky, yellowish hairs. Legs glabrous, and with small, 
distant punctures. Antenne, in both sexes, with the same 
number of joints; in the male the third and following 
joints are dilated, produced beneath, and imbricated, but 
not emarginated at their tips ; in the female they are long- 
obconic, compressed, slender. Last ventral segment of 
the male deeply indented. 

This large species differs from the brevicornis, F. in not 
having the elytra rugose nor confluently punctured ; it is 
also of a more elongated shape, not so much narrowed 
behind, the thorax shorter, the anterior tooth of which is 
much more and the posterior one rather less prominent, 
and the terminal aculeus of each elytron longer. The 
brevicornis is of a much darker color, and is easily dis- 
tinguished from it by its corrugated elytra. The levigatus 
bears a closer resemblance to the zmbricornis, L., but the 
antennee of the male, like those of the female, have only 
twelve joints, and the joints are not so large, and so close- 
ly imbricated. The color is the same in both, and they 
are nearly equally smooth; but the elytra of the zmbricor- 
nis are not very distinctly aculeated. Our species proba- 
bly approaches to the palparis, Say, which is described as 
being black, with the last joint of the maxillary palpi very 
conspicuously longer than the preceding joint.

yellow spot at base, a minute one on the outer margin be- 
hind the shoulder, a larger one before the middle, a trans- 
verse, slightly arcuated, slender band across the middle, 
and between this and the tip two spots transversely 
united. 

Length from 80 to 90 hundredths of an inch. 

C. nobilis, Harris. Catalogue, p. —. 

Halsey’s Collection, No. 226. 

Cabinet of the Boston Society, Nat. Hist. No. —. 

This fine and strongly characterized species varies con- 
siderably in the size and distinctness of the elytral spots. 
Of five specimens, known to me, three have the arcuated 
band interrupted into three transverse spots, which, how- 
ever, run together. In one there was the addition of a 
small, transverse, very faint spot just before the tip of each 
-elytron; and, in another, the band and all the spots were 
obsolete, except the round one before the middle of the 
disc. Jour of these specimens were taken upon Blue Hill 
in Massachusetts ; Mr. Halsey’s specimen was captured 
in Hartford, Connecticut. 

It is closely related to the Cuyrus speciosus, first de- 
scribed by Mr. Say in the Appendix to Keating’s “ Nar- 
rative of Major Long’s Expedition to the source of the 
St. Peter’s River, &c. ;” subsequently described and fig- 
ured in his “ American Entomology ;” and still more re- 
cently a figure of it has been published in Griffith’s Trans- 
lation of Cuvier’s Animal Kingdom, under the name of 
Crytus Hayu, G. R. Gray. The last name, of course, 
must sink into asynonyme. ‘The speciosus, besides being 
larger, has the thorax fasciated, and the elytral bands and 
spots differently arranged, and is otherwise sufficiently 
distinct from our C. nobilis.

subacuminated ; antennz pilose; thorax unarmed, ab- 
ruptly constricted behind. 

Length from 44 to 57 hundredths of an inch. 

Halsey’s Collection, No. 140. 

Body testaceous, pilose. Head with a longitudinal im- 
pressed line. Antenne a little longer than the body, 
joints elongated-cylindrical, terminal one obtusely rounded 
at tip, and nearly as long and large as the preceding one ; 
all of them pilose. Thorax a little wider than the head, 
longer than broad, rounded at the sides, abruptly contract- 
ed behind, granulated, pilose, and with an impressed dor- 
sal lme. Elytra paler than the head and thorax, pilose, 
elongated linear, rugose, or confluently punctured as seen 
under a microscope, and with three slightly elevated lines ; 
at tip each abruptly and triangularly narrowed on both 
sides, with the apex obtuse. Body beneath somewhat 
glabrous, sparingly pilose. Thighs simple ; tibize and tarsi 
slender. 

Entirely distinct as to the form of the thorax and ter- 
mination of the elytra from our other species of Srenoco- 
rus, to which genus I have doubtingly referred it. Com- 
pared with the Srenoeorus rigidus, of Mr. Say, which 
has also the elytra entire or simply subacuminate at tip, it 
is a much more slender species, the antennz not spined 
as in that insect, the thorax is differently shaped, and the 
color is not decidedly ferruginous, but of a dirty reddish 
yellow. I have seen only two specimens, one of which 
was captured in Louisiana. 


23. Lanta (Acanruocinus?) oBsoLeta, Olivier. 

Body above reddish gray, squamous ; antenne of the 
male very long, annulated with gray and dark brown; 
thorax bituberculated before, and tuberculato-spinous each 
side behind the middle ; elytra with dilated punctures, and 
three undulated, dark brown bands ; tips not emarginated, 
but obliquely truncated within.

L. obsoleta, Olivier, Entomol. 4, No. 67, p. 130, pl. 13, 
fig. 90. 


Halsey’s Collection, No. 121. 

Body covered above with appressed, dilated, short bris- 
tles, or linear scales of a reddish-gray color. Front naked, 
impunctured, with a longitudinal impressed Ime. Anten- 
nz more than twice as long as the body; joints slender, 
gray, with the terminal third of each brownish black. 
Thorax squamous, and punctured ; two transverse, naked, 
brown tubercles before the middle, and an acuminated 
one on each side before the base, which is abruptly con- 
tracted to the width of the anterior margin. Elytra with 
reddish-gray, appressed scales, and with distant, dilated, 
dark punctures ; three undulated, ragged, transverse, dark 
brown or blackish bands, convex backwards, one of which 
is more obsolete, before the middle, the second most dis- 
tinct, behind the middle, and the third, narrower, some- 
what interrupted, before the tips, which are attenuated, 
obsoletely and obliquely truncated, and divaricating at the 
suture, but not emarginated as in the cognate species. 
Legs griseo-squamous ; thighs abruptly clavated, and dark- 
er; tibia, near the upper and at the lower extremity, an- 
nulated with black or dark brown; tarsi blackish. Body, 
beneath, ferruginous, sparingly griseo-squamous ; abdo- 
men paler. 

The form of the thorax in this species closely resembles 
that of L. (Acanruocinvs) acanthura, Harris (Catalogue ;) 
but the anterior tubercles are quite distinct and not obso- 
lete as in that species; the intermediate elytral band is 
much broader; the tips of the elytra divaricate but are 
entire ; and the antenne are much longer, and more slen- 
der. 

This insect agrees with Olivier’s description and figure 
of the obsoleta, except in being rather smaller.

24. Lamia (Mesosa) rascicuLanris.* 

Thorax white ; elytra pale brown, variegated with dusky 
spots and elevated fasciculated points, whitish at base, and 
with an oblique whitish band behind the middle. 

Length 35 hundredths of an inch. 

Halsey’s Collection, No. 281. 

Head with a longitudinal impressed line on the front, 
sulcated between the antenne, which are rather longer 
than the body, and pale rufous, blackish at the tip of each 
joint. Thorax whitish, transverse, contracted abruptly 
behind, gradually before, punctured at the sides, and across 
the base and tip, rather unequal, with a small tubercle 
before the middle and one behind it, an impressed short 
line in the middle of the base ; lateral spines replaced by a 
slightly elevated tubercle on each side. Elytra pale brown, 
punctured ; humeral angles oblique ; a faint whitish band 
across the base, and a more distinct, oblique one, border- 
ed behind with black, sloping forwards at the suture, just 
behind the middle; sides between the base and bands 
dusky ; a small blackish spot near the suture behind the 
band, and another further back and contiguous to the out- 
er margin; a subsutural series of small, fasiculated, black 
points, another on the middle of each elytron, and several 
rather larger scattered over the surface, particularly to- 
wards the base, near the middle of which are two much 
more prominent than the rest; tips of the elytra obliquely 
truncated. Body, beneath, dusky or chocolate brown, 
densely covered at the sides of the breast, and sparsely on 
the abdomen with short, ashen-colored hairs. Thighs 
blackish brown at base, ashen at tip; tibise ashen, with a 
narrow blackish band on the middle and a broad one at 
tip; tarsi blackish. 

This species closely resembles L. macula, Say, which 1s 
much more convex, or not so much depressed, proportion- 
ally shorter and thicker, with a rather narrower, more

cylindrical thorax, with the punctures of the elytra more 
dilated, without the elevated fasciculated points at the 
base, besides other characters which sufficiently distinguish 
it from the fascicularis. Lamia alpha, Say, is a smaller, 
more slender, more parallel species, with the dorsal fascia 
much more oblique, &c. 


25. Monorcuus MELLITus, Say. 


Variety. Black; abdomen honey yellow; antennex 
feet and elytra rufous, the latter black at the tip. 

Length 85 hundredths of an inch. 

M. mellitus, Say. Boston Journ. Nat. Hist. vol. 1. p. 194. 

Halsey’s Collection, No. 263. A female. 

Head wider than the thorax, which 1s acutely constrict- 
ed between the middle and tip. Elytra rufous, each one 
separately rounded behind and tipped with black. Ter- 
minal joints of the abdomen blackish above. ‘Tarsi tinged 
with fuscous. 

This variety has not been noticed by Mr. Say. Com- 
pared with the abbreviatus, of Europe, the head is pro- 
portionally wider, and deeply indented between. the an- 
tenne ; the thorax is longer, nearly cylindrical ; the elytra 
are larger, and more obtusely rounded behind. The ab- 
breviatus is a much larger insect, with the abdomen and 
tips of the hindmost thighs black, and the elytra immacu- 
late. The dimidiatus, of Europe, is a smaller species than 
the mellitus ; the thorax more convex, not acutely con- 
stricted before the middle, the elytra proportionally long- 
er, attenuated from base to tip, and more acutely round- 
ed behind; the abdomen proportionally shorter, with the 
edges of the ventral segments whitish sericeous.

C. cinctus? EF. Entom. Syst. vol. i. part 2. p. 63. 

Halsey’s Collection, No. 176. 

Antenne fuscous, rufous at base. Front with an obso- 
lete longitudinal line, and with the thorax rufous, glabrous, 
impunctured. Elytra striato-punctate, black, with a broad, 
pale rufous or rufo-testaceous outer margin, which is nar- 
rower before, broader behind, and dentated near the mid- 
dle. Scutellum rufous, impunctured. Feet fusco-rufous, 
tibize at tip and tarsi darker, the former with a broad strong 
tooth on the outer edge near the end. Body, beneath, 
dark rufous, obsoletely punctured. 

This insect agrees better with the description of the 
cinctus than with that of the canellus. M. Fabricius says 
that the former inhabits South America and the latter 
Carolina. It may be a variety of the canellus in which the 
two black spots run together and unite with the black su- 
ture. Under this impression, and because it is a North 
American species, I have described it under the name of 
canellus, with a doubt however as to its identity. It has 
the form of Cotasris guercus, S. 


27. Gaeruca (ApIMoNIA) cRisTATA.* 

Black ; thorax rufous with a black disc and two im- 
pressed spots; elytra with the margin dilated, a lateral 
elevated and an abbreviated impressed line. 

Length from 17 to 19 hundredths of an inch. 

G. A. unicolor, Harris, Catalogue, p. —. 

Halsey’s Collection, No. 218. 

Black, above and beneath. Front, between the anten- 
nz carinated, vertex indented. Antennz about two- 
thirds the length of the body ; first joint obconic, second 
globose, third very short obconic, the two together shorter 
than the fourth, which, with the following ones, is elonga- 


Plate I. Fig. 11. 


NORTH AMERICAN COLEOPTERA. 91 


ted obconic; terminal joint oblong-ovate, acuminated. 
Thorax impunctured, quadrate, glabrous, rather broader 
than long, slightly contracted behind, the lateral edges 
acute ; convex, black from the anterior to the posterior 
margin, sides more or less obscurely rufous; a deep in- 
dentation each side of the centre. Elytra purplish black, 
confluently but not deeply punctured, oblong quadrate, 
rounded behind, with the lateral margin horizontally dilat- 
ed, and elevated on the edge, a submarginal elevated line 
beginning at the humerus, and on a short, longitudinal fur- 
row within the elevated line ; base with an obsolete tu- 
bercular elevation in the middle; suture slightly elevated. 
Breast, abdomen beneath, and feet deep black. 

This species probably bears a close resemblance to the 
atripennis, S., which has the thorax and body beneath ru- 
fous. 

The specific name unicolor was applied to specimens 
in which the rufous color of the sides of the thorax was 
indistinct or obsolete. It is, however, inappropriate, and 
is therefore changed.
